CARBURETER.

Specification of Letters Patent.

Application filed August 8,1904. Serial No- 219,982-

[0 all whom it may concern:

Be it known that I, WALTER THIEM, a subject of the King of Prussia, German Emperor, residing at Halle-on-the-Saale, in the Kingdom of Prussia, German Empire, have in vented a new and Improved Uarbureter, of which the following is a specification.

This invention relates to a carbureter in which the carbureting liquid is introduced in separate small quantities into the carbureter, corresponding to the quantity or quantities of air, and is distributed in said carbureter upon a large surface in order to be completely evaporated.

The principal feature of the invention consists in the arrangement of the carburetor and of the suction device through which the finished mixture is led away within a common casing that is closed on all sides and within which said parts are surrounded by the water therein contained. By this means a temperature equalization takes place between the generated gas and the water used in the suction device and the carburetor is prevented from freezing, and its effect is increased. The continuous movement of the water, owing to the rotation of the suction apparatus, prevents collection of cold layers of water, thereby further increasing the capacity of the carbureter.

My invention is illustrated in the accompanying drawings, in which Figure 1 is a front view of the improved device. Fig. 2 is a view of the interior of the apparatus; and Fig. 3 is a section on line A B, Fig. 2, parts being shown in elevation.

a is the suction apparatus, 1) the carbureter, and Z a casing surrounding said parts a and b, said casing being filled with water so far that the carbureter is completely surrounded with the same. The air enters through the pi e c. The carbureting liquid is distributed by the distributer e, which is connected by a pipe 72. with the carbureter andis actuated from the suction apparatus a by a chain and chainwheels f g.

A bucket conveyer is arranged within the distributer 6, so as to deliver hydrocarbon in separate quantities to the carburetor and proportional to the amount of air that is sucked in through the pipe 6. It is therefore necessary to provide motive power for the bucket conveyer, and this is done by means of the chain-gear f g. When said suction apparatus is rotated, it draws in the mixture of gas and air escaping from the carbureter at d and collecting within the space Zr: and forces said mixture through the pipe 71 into, a bell or other suitable collector.

In view of the fact that the suction apparatus draws in and conveys only a finished mixture no special gas-meter is necessary to drive the feeding device in such a manner that the carbureting liquid is fed in quantities corresponding to the air drawn in.

In order to prevent the water contained in the casing Z from evaporating and from mixing with the generated gas, the water may receive a layer of oil. As the water is in contact with the walls of the casing Z, equalization of temperature takes place between the water and the atmospheric airthat is to say, the water which is cooled by the evaporation is again heated by the influence of the outer atmosphere.

What I desire to secure United States is- 1. In an apparatus of the character described, the combination of a casing closed to all sides, a carbureter-coil within said casing, an air-inlet pipe communicating with said coil, a suction-drum entirely within the cas-v ing, an outlet-pipe leading from said drum, and a distributer mounted on said casing for feeding liquid hydrocarbon to said coil.

2. In an apparatus of the character described, the combination of a casing closed to all sides, a carbureter-coil within said casing, an air-inlet pipe communicating with said coil, a suction-drum entirely within the casing, an outlet-pipe leading from said drum, a distributer mounted on said casing for feeding liquid hydrocarbon to said coil, and means connecting the drum and the distribu ter to cause said parts to operate in unison.

3. In an apparatus of the character described, the combination of a casing closed to all sides, acarbureter-coil within said casing, an air-inlet pipe communicating with said coil, a suction-drum entirely within the casing, an outlet-pipe leading from said drum, a distributer mounted on said casing for feedby a patent of the ing liquid hydrocarbon to said coil, and Inwitness whereof Ihave hereunto set my means connecting the drum and the distribuhand in presence of two witnesses.

ter to cause said parts to operate in unison; WALTER THIEM said casing containing a space for a cooling medium and above said space a second space Witnesses:
